Public bug reported: After upgrading from Ubuntu wily (15.10) to xenial (16.04, LTS), the NetworkManager control applet (nm-applet) ceased to show up. While running wily and even prior, I had modified /proc's "hidepid" argument to be 2, in accordance with hardening best practices in order to only allow users to see their own processes. Nm-applet was working just fine.
Based on this Debian bug (https://bugs.debian.org/cgi- bin/bugreport.cgi?bug=819808), I changed hidepid back to 0 (the default, which lets users see everyone's processes) and it's working again. Given that nm-applet was working just fine in wily and upgrading to xenial broke it, it seems like a regression.
